Manhattan Project National Historical Park

The dominant safety concern at Manhattan Project National Historical Park isn't the weather — it's the surrounding community's crime rate. Los Alamos County recorded a violent crime rate of 795.2 per 100,000 residents in 2023, which runs significantly higher than the national average and warrants attention for families visiting the area's scattered sites across town.

When planning your visit, avoid leaving valuables visible in your vehicle, particularly at the less-trafficked outlying sites like the Pajarito Road areas where parking is isolated. Since the park spans multiple separate locations rather than a single enclosed grounds, map your route between sites in advance so you're not idling in unfamiliar spots after dark. The handful of recorded hail and thunderstorm wind events (five total in recent data) are minor by comparison, but keep a rain layer accessible if you're moving between outdoor exhibits.
